Sittings of the Tribunal restricted on weekends and public holidays; ordinary sitting hours prescribed for regional benches. Rule 43 provides that the Tribunal shall not ordinarily hold sittings on Saturdays, Sundays or other public holidays, and specifies the ordinary daily sitting hours for regional benches: New Delhi, Bombay and Madras observe a mid morning to early afternoon session with an afternoon resumption, while Calcutta follows slightly earlier start and end times with a comparable afternoon session.
